sometime in the night something happened.

All my clients off of one ap are associating and dropping constantly. (every few min to few sec).
I've thought that someone might have turned something on to cause interference to I decided to move the radios to another frequency. Completed that but that didn't fix the issue.

The current setup: clients are xr9 cards on 411 boards with power in the 60's and still showing high ccq and throughput. (high throughput and ccq make me think it isn't interference but the only other time i've seen such a symptom a competitor had turned on a facility on the freq I was using) channel spacing is 5mhz. The ap was originally broadcasting on 917. I moved a few clients to 922 (2442 on the xr9 cards with the conversion) and set the app to 922mhz. (I confess I did not check this with a spectrum analyzer)

I am currently out at the facility and have found that I can only get into the ap in question sporadicaly. Usually I get the error 'could not connect to 'mac address' (port 20561) timed out'.

I have rebooted my machine, disabled and enabled my nic but still nothing reliable. I can get into the ap if I put my machine on it's cat5 directly but not if I connect to the switch the ap is plugged into. So I thought switch or port failure. Tried different ports and replaced with a known good switch. Still the same issue.

I tried putting the bh and ap back to back and bypassed the switch but the radios still associate and re-associate.

Why are my radios suddenly doing this association dance. Interference, bad board in the ap, failing radio card? Only thing I haven't done is replace hardware. What a pain. Any thoughts before I do that?

Any help or insight is appreciated

you have a good power source?

i mean, maybe it's an electrical trouble, can you check that?.

off: if you think that it's a hardware issue, you should post all your hardware devices.

I am currently out at the facility and have found that I can only get into the ap in question sporadicaly. Usually I get the error 'could not connect to 'mac address' (port 20561) timed out'.

can you try to log in with ip address??? not with MAC address

IP address: you mean simply put that in in winbox and log in or do you mean webbox. I'll try both.

I have new configured hardware that I am going out with today as well.

Power: It is a solar powered facility with several other radios. None of the other radios are having trouble and the voltage etc all looks good. I did not try swapping out the cat5 cable to see if something was wrong there. I'll try hardware first as running a new cable will also be a pain but I'm bringing it with me.

Hardware having trouble is a 411ah with xr9 card and 15dbi panel lvl 4. 60m cable run to enclosure with power. Other equip on site is a 433 board with an xr9 and xr5 card. 70m cable run. this is having no trouble.

I'll post back

So I was able to log in via winbox with the IP not the mac.

I put new hardware up and was able to log in. as soon as I set the unit to the proper frequency and had clients connect it kicked me out with the above error.

Found the problem. My network is, ugh, a bridge. Someone plugged in a router backwards or something of the nature. I found the client in question and disabled the nic remotely.

All is fine now.

Now I have learn how to route this setup so this doesn't happen again.

many thanks
